Xbox game pass streaming - 'Play' option not showing

Hi all,

I would like to try the new game streaming feature on my android phone, but I can't seem to get it working.

This is my setup:

• Samsung Galaxy S7 with Android v.8
• The Xbox game pass app, downloaded from the Google Play store (though I have also tried the Xbox Game Pass (Beta) app with the same results)
• An Xbox Game Pass Ultimate subscription valid until January next year
• An xbox one controller connected via bluetooth (the app definitely recognises that the controller is connected because I can use it to navigate the menus)
• An internet connection via my home wifi (though I have also tried 4g)

My understanding from reading the confusing articles about it, is that, when you have a pad hooked up, a new 'row' should appear on the Game Pass app labelled 'play' that should show games you can stream. This does not appear for me and I can't find any
option anywhere to stream games in the app.

:)
